Set up LLM providers

Last validated: Apr 9, 2026

Aperture by Tailscaleis currently in alpha.

Aperture routes LLM requests from configured LLM clients to upstream providers on behalf of your users. Each provider requires API credentials and a configuration entry in the Aperture configuration. After you configure a provider, any LLM client set up to use Aperture can access models from that provider automatically.

Aperture supports all the main LLM provider types, each with a different authentication method and API format.

Any provider that offers an OpenAI-compatible API (such as Anthropic, OpenAI, or Groq) can be configured directly in the Aperture configuration without a dedicated guide. Set the provider's baseurl, apikey, and models fields, and Aperture handles the rest.

The following guides cover providers that require additional setup beyond a base URL and API key. Refer to the provider compatibility reference for the full list of supported providers, API formats, and compatibility flags.

Use Vertex AI with Aperture \ \ Configure a Vertex AI provider in Aperture with a GCP service account and key file so your team can access Gemini and Claude models through Aperture. Set up a Vertex AI Express provider \ \ Configure a Vertex AI Express provider in Aperture with a Google Cloud API key so your team can access Gemini models through your tailnet without managing service accounts.
